LAMP-SHADE SUPPORT.

Application filed November The invention relates to a support for lamp shades, the support being of the type which clamps directly on an electric light bulb by means of spring clamps, but which will permit an adjustment of the shadewith respect to the bulb.

If a certain type of shade is to be used on a number of electric light bulbs of the same or different designs and it is found that the 1 length of the shade is too great in proportion to the pedestal of the lamp this invention enables the decorator to raise the shade in pro portion to the height of the lamp so as to get the desired effect. It has been found neces- V sary a times to have specially made a number of shades, as the regulation size shade obtainable was found too long but by use of this invention stock sizes of shade can be used and adjusted to the desired height above the lightbulb.

The invention will be described in detail in connection with the accompanying drawing in which two embodiments are shown by way of example,

Fig. 1 a vertical section of one form of shade support,

Fig. 2 is a plan view shown in Fig. 1,

Fig. 3 is a vertical section of another form of shade support,

Fig. -l is a plan view shown in Fig. 3,

Fig. 5 is a detail view of one of the brackets in which the shade supporting member of Fig. 3 is mounted, and

Fig. 6 is an alternative form of bracket for mounting the shade supporting member.

In the embodiment shown in Figs. 1 and 2, is an electric light bulb upon which the shade support is clamped by means of springs 2 arranged at angles of 120 with respect to each other. A stud 3 provided with a vertical hole 4 projects from each spring 2. The holes 4 are adapted to slidably receive the legs 5 of a supporting member consisting of the said legs and a ring 6 to which the legs are joined. The legs are locked in any desired position by means of set screws 7. The upper ends of legs ovare curved in conformance with the of the shade support of the shade support 7 23, 1926.

surface of the bulb so that they can be adjusted close to the same.

In the embodiment shown in Figs. 3, 4 and 5 two clamps 10 and 11 are arranged at right angles to each other, and joined at their intersection. The arms of clamp 10 are provided with studs 12 consisting of the parts shown in detail in Fig. 5, namely, a base 1nember 13 rigid with the arm of the clamp, and a swivel member 14 pivoted thereto by means of a pin 15 projecting through hole 16. The end of the pin is riveted or spun over against the surface 17 in such a way as to permit the swivel member to turn with respect to the base member, but to hold them in any adjusted relation. The two legs 18 of the supporting member 19 slide in holes i of the swivel memhers, and are held in adjusted position by set screws '7. p The supporting member 19 is externally threaded to receive the threaded collar 21 of shade 9. It will be seen that this modification can be adjusted angularly as well as vertically.

in the alternative form of bracket for" mounting the shade supporting member on the clamp shown in Fig. 6, the set screw is replaced by a spring 22, which frictionally engages the legs of the supporting member. The spring may be secured to the stud in any convenient manner, as for example by the screw 23.

The drawings illustrate merely the principles of our invention. The details of construction of the support will vary depending 011 the types of stock shades or special shades that are to be used.

Having described our invention, we claim:

A lamp-shade support comprising a lamp engaging-frame, a shade-supporting frame, coupling studs rotatably secured to one of said frames and having through-holes perpendicular to the axis of the studs, and

straight legs on the other frame slidably engaged in said holes. I

In testimony whereof the foregoing specification 1s slgned.
